Configuring OSPF

dead-interval:

Indicates the number of seconds that a neighbor router waits for a hello
packet from the current router before declaring the router down. The value
can be from 40– 65535 seconds. The default is 40 seconds. Beginning
with version 03.2.00 of the Multi-Service IronWare software, the rules
described in

“Rules for OSPF dead interval and hello interval timers”

on

page 178 apply regarding this timer.

hello-interval

Represents the length of time between the transmission of hello packets.
The value can be from 1 – 65535 seconds. The default is 10 seconds.
Beginning with version 03.2.00 of the Multi-Service IronWare software, the
rules described in

“Rules for OSPF dead interval and hello interval timers”

on page 178 apply regarding this timer.

MD5-authentication activation wait
time

The number of seconds the device waits until placing a new MD5 key into
effect. The wait time provides a way to gracefully transition from one MD5
key to another without disturbing the network. The wait time can be from 0
– 14400 seconds. The default is 300 seconds (5 minutes).

MD5-authentication key string The

MD5

key is a number from 1 – 255 and identifies the MD5 key that is

being used. This parameter is required to differentiate among multiple
keys defined on a router.
By default, the authentication key is encrypted. If you want the
authentication key to be in clear text, insert a 0 between key and string.
For example,
Brocade(config-if-e10000-1/8)# ip ospf 1
md-5-authentication key-id 5 key 2 morningadmin
The software adds a prefix to the authentication key string in the
configuration. For example, the following portion of the code has the
encrypted code “2”.
ip ospf 1 md-5-authentication key-id 5 key 2 $on-o
The prefix can be one of the following:

0 = the key string is not encrypted and is in clear text

1 = the key string uses proprietary simple cryptographic 2-way
algorithm.

2 = the key string uses proprietary base64 cryptographic 2-way
algorithm (only for Brocade NetIron XMRBrocade MLX series devices)

mtu-ignore

A database description packet is rejected if the interface MTU specified in
the DBD packet is greater than the MTU of the interface shared between
the neighbors. To disable the mismatch condition set “mtu-ignore”.
By default, the mismatch detection is enabled

passive

When you configure an OSPF interface to be passive, that interface does
not send or receive OSPF route updates. By default, all OSPF interfaces are
active and thus can send and receive OSPF route information. Since a
passive interface does not send or receive route information, the interface
is in effect a stub network. OSPF interfaces are active by default.
Note: This option affects all IP subnets configured on the interface. If you
want to disable OSPF updates only on some of the IP subnets on the
interface, use the ospf-ignore or ospf-passive parameter with the
ip address command.
